Hey y’all, it’s your boy Matthew Taylor here. I’ve got a funny story to tell you about the time I was trying to find the oil pressure sending unit on my small block Chevy.
So, I’m under the hood, feeling like a real mechanic, you know? I’ve got my toolbox open and I’m ready to tackle this task.
I pull out my trusty manual and start looking for the oil pressure sending unit. I’m searching and searching, but I can’t seem to find it anywhere. I start getting frustrated, so I decide to ask my buddy for help.
I go knock on his garage door and he opens it up, looking at me like I’m crazy. “Dude, what are you doing?” he asks.
“I can’t find the oil pressure sending unit on my small block Chevy,” I tell him. He starts cracking up, laughing so hard he can barely stand. “Matthew, you don’t have a small block Chevy,” he says. “You have a big block.”
I couldn’t believe it. I had been looking for the oil pressure sending unit on the wrong engine the entire time! Talk about embarrassing.
But hey, we all make mistakes, right? So, to save you from the same fate as me, I’ve decided to write this article on where to find the oil pressure sending unit on a small block Chevy. Let’s get started.

What Is The Oil Pressure Sending Unit?
The oil pressure sending unit is a sensor that measures the oil pressure in your engine. It’s an important component of your vehicle’s lubrication system, as it helps to ensure that the oil is flowing properly and lubricating all of the moving parts in the engine.
The oil pressure sending unit is typically located on the engine block, near the oil filter. It’s usually attached to the engine with a bolt and has a wire connecting it to the dashboard gauge or warning light.
Why Is The Oil Pressure Sending Unit Important?
The oil pressure sending unit is important because it helps to alert you to any issues with the oil pressure in your engine.
If the oil pressure drops too low, it could cause damage to the engine. On the other hand, if the oil pressure gets too high, it could cause the oil to break down and lose its effectiveness as a lubricant.
By keeping an eye on the oil pressure, you can help to prevent serious problems from occurring with your engine.
How Do You Test The Oil Pressure Sending Unit?
To test the oil pressure sending unit, you’ll need a few tools:
- A digital multimeter
- A socket set
- An oil pressure gauge
First, locate the oil pressure sending unit on your engine. It should be located near the oil filter, as mentioned earlier.
Once you’ve found it, use the socket set to remove the bolt that holds it in place. Then, attach the oil pressure gauge to the sending unit and start the engine. The gauge should show the oil pressure in the engine.
Compare the reading on the gauge to the manufacturer’s recommended oil pressure range for your vehicle. If the reading is outside of this range, it could indicate a problem with the oil pressure sending unit or with the oil pressure in the engine itself.
How Do You Replace The Oil Pressure Sending Unit?
If you’ve determined that the oil pressure sending unit needs to be replaced, you’ll need to follow these steps:
- Shut off the engine and let it cool down.
- Locate the oil pressure sending unit on the engine block. It should be near the oil filter.
- Use a socket set to remove the bolt that holds the sending unit in place.
- Disconnect the wire from the sending unit.
- Remove the old sending unit from the engine.
- Install the new sending unit in its place, making sure to tighten the bolt securely.
- Reconnect the wire to the new sending unit.
- Start the engine and check the oil pressure to make sure it’s within the recommended range.
Frequently Asked Questions
What Causes The Oil Pressure Sending Unit To Fail?
There are a few reasons why the oil pressure sending unit might fail:
- Wear and tear: The sending unit is subjected to a lot of heat and pressure, which can cause it to wear out over time.
- Contamination: If dirt or debris gets into the sending unit, it can cause it to malfunction.
- Internal problems: The sending unit could have internal problems that cause it to fail.
What Are The Symptoms Of A Failed Oil Pressure Sending Unit?
Here are a few signs that your oil pressure sending unit might be failing:
- Inaccurate oil pressure readings on the dashboard gauge
- Frequent oil pressure warning lights on the dashboard
- Loud knocking noises coming from the engine
- Excessive oil consumption
Can I Drive My Vehicle If The Oil Pressure Sending Unit Is Faulty?
It’s generally not a good idea to drive your vehicle if the oil pressure sending unit is faulty. If the oil pressure drops too low, it could cause serious damage to the engine.
It’s best to get the sending unit replaced as soon as possible to avoid any issues. If you’re unsure whether or not the sending unit is functioning properly, it’s a good idea to have it checked by a mechanic.
